Subject: refactor: move definition of Deno.build from "runtime" to "core"
 (#18036)

We use information about build in several extension crates like
"ext/node" or "runtime/". In an effort to move "fs" APIs to a separate
crate it is a prerequisite to have this information available outside
of the "runtime/" crate.

This commit moves definition of "build" object to "Deno.core" that is
later forwarded to "Deno.build".
